On the Ground State of Two Flavor Color Superconductor
arXiv:hep-ph/0505061 · doi:10.1088/0256-307X/23/3/011
Abstract
The diquark condensate susceptibility in neutral color superconductor at moderate baryon density is calculated in the frame of two flavor Nambu-Jona-Lasinio model. When color chemical potential is introduced to keep charge neutrality, the diquark condensate susceptibility is negative in the directions without diquark condensate in color space, which may be regarded as a signal of the instability of the conventional ground state with only diquark condensate in the color 3 direction.
